CEBEAL-GRAIN-HULLING SYSTEM.

To all whom it may comer-n:

Be it known that we, FRANK EMENEGGER and J our; H. -WESTFALL, citizens of the United States of America, residing at Petaluma, in the county of Sonomaand State of California, have invented certain new and useful Improvements in Cereal-Grain- Hulling Systems, of" which the following is a specification.

' and operating upon This invention relates to certain new and useful improvements in cereal grain hulling systems. I v

The primary object of the present invention is the provision of a means for hulling cereal grains without grinding or mealing the same and is especially adapted for repeatedly 'hulling barley, oats and rice in large quantities and in perfect condition. I Afurther object of the invention is'the provision of a cereal huller combining differentforms of cooperating means successively for acting upon the stock, particles being pneumatically transferred during the operation of the device resulting in a clean product of entire grain.

A still further object of the device is to provide a hulling mill :Eor cereal grains arranged for receiving the grain with its hulls the stock for furnishing clean whole grain with the bulls and waste suitably collected, arrangement being made for conserving the stock for repeating the entire operationv upon any uncleaned groats the mill.

before the same can leave in view and With these eneral objects others that w appear as the nature of the invention is better understood, the same consists in the construction, combmat1on, and arrangement of parts hereinafter more fully descri ed, illustrated in the accompanying drawings, and then claimed.

In the drawings forming a part of this application, and in which like designating characters refer to corresponding parts throughout the several views,

hulls and dust or polish admitted thereto through the stock feed pipe 24 leading from the disintegrator housing 13. The reel 11 is slightly inclined and arranged with'an operating shaft 25 having a driving pulley 26,

it being noted that the disintegrator spmdle 18 15 arranged with a similar pulley 27 The revolving of the reel 11 scrapes or scours the stock arranged therein so that the I fi ne dust or polishpasses through the sieve-. like wall 23 of the reel to a screw conveyer 28 arranged therebeneath and operated'bya An outlet spout 30 for the. dust 1s arranged for the conveyer '28 havin a arranged at any desirsfiile position.

A metallic tray 40 is arranged beneath the vibrating screen .38 adapted for feeding the groats which pass through the screen to an upright aspirator 41 through a communicating pipe 42 arranged between the inlet 43. of the'aspirator 41 and the outlet'44 of the tray 40 inthe adjacent side of the casing of the aspirator 12.

casing .35 for the inlet, thereof connected I with the upright ,aspirator 41 by means of a suction trunk 46 while a branch pipe 47 from .said trunk communicates with the in- "terior of the vibrating aspirator casing 35. An inner or discharge trunk 48 leads from the outlet of the fan 45 to a hull collector 49 arranged with a discharge pipe 50 for the waste from the mill.

The vibrating aspirator 12 separates the hulls from thegroats by reason of the spreading :of the stockby the vibrating motlon or the screen 38 permitting'the free action of the air drawn in by the fan 45 through .the branch pipe 47. The groats pass through the tray to the upright asxpirator 41 while the main air current lifts the hulls within the casing 35. and the counterbalanced air being of insuificient strength to lift the groats, while the-hulls pass upwardly to the fan and through the trunk 48 to the collector 49 having a The tail over from the vibrating aspirato'r 12 passes through a conduit 51 leading from the outlet 52 of the feed spout 34 and the outlet 53 of the vibrating screen 38 to the 5 receiver 54 toa return elevator 55.-v

56 arranged with buckets 57 thereon for transferring the tailings from the vibrating aspirator 12 back to the stock hopper 14 by elevating the tailings and discharging t em through'the spout 58 of the elevator casing '59. An operating pulley 60 is provided for the elevator belt 56. The up-- right sflpirator 41 is arranged with alternate ba e plates 61 over which the grain falls from the inlet 43 thereof to the discharge or sacln'ng spout 62 arranged for the finished groats. at the bottom of the upright aspirator 41. A controlling gate 63 guards the entrance to the aspirator41 and it will be understood that the fan 45 by means of the suction trunk 46 provides a constant updraft through the aspiiator 41 cleaning the grain from all remaining hulls and dust, such waste products being thereby trans-' 65 ferred to the hull collector 49.
